GUIDE FOR ROLLING MILLS Filed March -26, 1928 2 Sheets-Sheet 2 ingsurface has only a relatively short forward projection from the reducingpass, instead of extending, as usual, for the full length of the guide.This construction per mits a roller 10 to be incorporated within thelength of the guide, said roller having its axis at right angles to thedirection of travel of the stock in the guide. Said roller 10 is sojournalled either in the guide itself, or independently thereof asshown, as to contact on its periphery with said stock, thereby to moveit longitudinally, due to rotation of said.

roller 10 in the same direction as conveyor rollers 2, 2, through themedium of gearing 11 from the shaft 6. In this way, without anysacrifice of accuracy in guiding, pieces of stock so short that theywould become stuck in any ordinary delivery guide, are readily handledin and promptly discharged from the guide, by the forward motionimparted to said pieces by the driven roller 10. In addition, theincorporation of this roller 10 in the guide lessens the danger of apiece jamming therein, as sometimes happens when the adjustment of theguide, to the line of the pass or to the section of the stock, isfaulty. And if a cobble does occur, the guide can be freed much morereadily than an ordinary guide because of the better access afl'orded toits interior from its outer end.

As shown in Fig. 3, the presence of the roller 10 prevents the hotbillet or bloom from bending down, notwithstanding the absence ofsupport therefor which results from the the omission to extend outwardlythe lower section 8 of the guide. The same is true of the modified formof roller designated at 12 in Fig. 4, and having a peripheral groove 13to receive the lower corner of the billet or bloom, thereby to eliminatethe possibility of any twisting. In both forms, the cooperation existingbetween the driven roller, incorporated in the guide, and the stationaryguide sections 7 and 8 serves to confine the billet or bloom laterallyin every direction while at the same time leaving it free to be movedlongitudinally by said roller, as soon as released by the reducingrolls. In other words, the use of such a roller makes it possible toemploy a guide that is long enough to hold the billet straight, and thatstill does not have to fit the billet with undue closeness.

With the driven gu ide roller supported, as shown, independently of theother members of the guide structure, the vertical adjustment of thelower roll of the stand of rolls 1, 1, by any suitable adjusting means 11, maintains the correct alinement between the reducing pass and thesurface of said driven guide roller. However, my invention is notlimited to such independent support of the driven guide roller, but whatI claim and desire to secure by Letters Patent of the United States isas follows 1. The combination with a stand of reducing rolls of arolling mill and a delivery guide adjacent the discharge side of thepass between said rolls, to engage with and maintain the direction ofthe rolled product as it emerges from said pass, said guide havingincorporated therewith, in close proximity to said pass, a driven rollerto procure the discharge of the rolled product from said guide, aftersaid reducing rolls are no longer effective to impart movement to thelast end of said product.

2. In a delivery guide for rolling mills, a relatively elongated portionproviding interior guide surfaces to engage and maintain the directionof the rolled product as it emerges from the reducing pass between apair of rolls, a shorter portion opposing said elongated portion, and adriven roller supplementing said shorter portion and adapted, byengagement with said rolled product, to insure the latters dischargefrom said guide, following the emergence of the last end of said rolledproduct from the reducing pass.

3. In a delivery guide for rolling mills, a

pair of rolls, a shorter portion opposing said" elongated portion, and adriven roller supplementing said shorter portion and adapted, byengagement with said rolled product, to insure the latters dischargefrom said guide, following the emergence of the last end of said rolledproduct from the reducing pass, the axis of saidroller being at rightangles to the line of movement of the stock through said guide, and saidroller cooperating with said guide portions to maintain the rolledproduct in its line of delivery, in the absence of any twisting orlateral deflection.

4:. The combination with a stand of reducing rolls, of a delivery guidetherefor having incorporated therein a driven roller to engage andforward the rolled product after the last end of the latter has clearedsaid rolls, and means for vertically adjusting the lower roll of saidstand, to maintain alinement between the reducing pass and said drivenguide roller.

5. The combination with a stand of reducing rolls, of a series ofconveyor rollers to receive the rolled product from said reducing rolls,and a delivery guide interposed between said reducing rolls and saidconveyor rolls, said delivery guide having incorporated therein a drivenroller to engage and forward the last end of the rolled product, whenthe latter has cleared said reducing rolls.

6. The combination with a stand of reducing rolls, of a series ofconveyor rollers to receive the rolled product from said reducing rolls,a delivery guide interposed between said reducing rolls and saidconveyor rolls,

said delivery guide having incorporated therein a roller to engage andforward the last end of the rolled product, when the latter has clearedthe reducing rolls, and common driving means for said conveyor rolls andsaid guide roller.
